A FUNGICIDAL COMBINATION, COMPOSITION, AND USE THEREOFFIELD OF INVENTION
[0001] The present invention relates to a fungicidal combination. Particularly, the present invention relates to a fungicidal combination comprising systemic fungicide and salicylic acid, salts or analogues thereof. The present invention also relates to a fungicidal composition comprising said fungicidal combination, and methods of using thereof for controlling fungal infestation in plants, crops, or parts thereof.BACKGROUND
[0002] Fungicides play an important role in agriculture in controlling, eradicating, or preventing attack and damage to crops by fungal pathogens, thus safeguarding growth, health and yield of the crop. However, constant use of conventionally known fungicides has been generating resistance in fungal pathogens, thus creating a need for new fungicides or combinations of fungicides which act synergistically. The need for responsible environmental sustainability also poses a requirement for safe and effective fungicides which achieve the purpose in minimal doses.Systemic fungicides are widely used to control a variety of fungal diseases. A systemic fungicide appears to be selective because it is toxic to only a single site within the fungus. This can cause problems, since a single change in the fungus can result in resistance to the fungicide. With a need to maximize the benefit, there is a need to combine these fungicides with agents which will help provide optimal effect with reduced dosages. There is therefore a need for effective and synergistic fungicidal solutions comprising multi-site fungicides, especially copper-based and sulphur-based fungicides.OBJECTS OF THE INVENTION
[0003] The present invention addresses the above unfulfilled requirement of the hour and targets to fill up the void for newer, effective, and synergistic fungicidal combinations and resulting solutions. It is an object of the present invention to provide fungicidal solutions which are effective at lower doses. Therefore, it becomes an object of the present invention to provide a novel, effective fungicidal combination comprising a systemic fungicide; and salicylic acid, salts or analogues thereof. It is an object of the present invention to provide a novel, effective fungicidal combination comprising a systemic fungicide; and salicylic acid, salts or analogues thereof. It is an object of the present invention to provide a synergistic fungicidal combination comprising a systemic fungicide; and salicylic acid, salts or analogues thereof. It is an objective of the present invention to provide a method of controlling fungal infestation of a plant, a crop, or a part thereof by applying said combination or a composition comprising said combination. It is an objective of the present invention to provide a method of controlling fungal disease in a plant, a crop, or a part thereof by applying said combination or a composition comprising said combination. It is an objective of the present invention to improve plant health, growth and yield by applying said combination or a composition comprising said combination. It is also an objective of the present invention to reduce the dosage of the fungicide without affecting the efficiency of controlling fungal infestation in a plant, a crop, or a part thereof.BRIEF SUMMARY

[0112] A greenhouse trial was conducted on potted tomato plants infectedwith early blight. A high dose of prothioconazole at 1 g ai / ha was compared to individual doses of prothioconazole and potassium salicylate at various rates(reduced for prothioconazole) and combination of prothioconazole andpotassium salicylate, with prothioconazole applied at reduced dosage incombination.Table 1: Efficacy of prothioconazole and potassium salicylate on early blight disease in tomatoExample 2: Efficacy of fluxapyroxad and potassium salicylate on fungal disease A greenhouse trial was conducted on potted soybean plants infected with target spot. A high dose of fluxapyroxad at 10 g ai / ha was compared to individual doses of fluxapyroxad and potassium salicylate at various rates (reduced for fluxapyroxad) and combination of fluxapyroxad and potassium salicylate, with fluxapyroxad applied at reduced dosage in combination.Table 2: Efficacy of fluxapyroxad and potassium salicylate on target spot disease in soybeanExample 3: Efficacy of fluoxastrobin and potassium salicylate on fungal disease A greenhouse trial was conducted on potted soybean plants infected with target spot. A high dose of fluoxastrobin at 96.4 g ai / ha was compared to 5 individual doses of fluoxastrobin and potassium salicylate at various rates (reduced for fluoxastrobin) and combination of fluoxastrobin and potassium salicylate, with fluoxastrobin applied at reduced dosage in combination.Table 3: Efficacy of fluoxastrobin and potassium salicylate on target spot disease in soybeanExample 4: Efficacy of fluoxastrobin and potassium salicylate on fungal disease
[0113] A greenhouse trial was conducted on potted pepper plants infected with Botrytis. Individual doses of fluoxastrobin and potassium salicylate, and 5 combination of fluoxastrobin and potassium salicylate.Table 4: Efficacy of fluoxastrobin and potassium salicylate on Botrytis infection in pepperExample 5: Efficacy of fluazinam and potassium salicylate on fungal disease
[0114] A greenhouse trial was conducted on potted pepper plants infected 10 with Botrytis. A high dose of fluazinam at 230 g ai / ha was compared to individual doses of fluazinam and potassium salicylate at various rates(reduced for fluazinam) and combination of fluazinam and potassium salicylate, with fluazinam applied at reduced dosage in combination.Table 5: Efficacy of fluazinam and potassium salicylate on Botrytis infection in pepperExample 6: Efficacy of fluazinam and potassium salicylate on fungal disease
[0115] A greenhouse trial was conducted on potted tomato plants infected with early blight. A high dose of fluazinam at 3.08 g ai / ha was compared to individual doses of fluazinam and potassium salicylate at various rates (reduced for fluazinam) and combination of fluazinam and potassium salicylate, with 5 fluazinam applied at reduced dosage in combination.Table 6: Efficacy of fluazinam and potassium salicylate on early blight in tomatoFrom the above examples 1-6 and tables 1-6, it can be observed that a combination of systemic fungicides such as prothioconazole, fluoxastrobin, fluazinam, fluxapyroxad when combined with potassium salicylate provided more than additive effect in controlling fungal diseases such as early or late blight in tomato, target spot in soybeans, and Botrytis in pepper. Thus, it is evident that the combinations of the present invention provide synergistic control / more than additive effect in controlling a variety of diseases or fungal pathogens in a wide spectrum of crops. Also, it was observed that when the dose of the fungicide was reduced to 10% of original dose and combined with potassium salicylate, control of fungus / fungal disease near to or equivalent to the higher dose was obtained. This establishes a crucial role of salicylic acid, its salts or analogues in better pest management with reduced fungicide use and thus, making sustainable practices possible.Abbreviations in examples:Cu = CopperSA = Salicylic acidKSA = Potassium salicylateg / L or g ai / L = Amount of active ingredient in grams per litremg / L or mg ai / L = Amount of active ingredient in milligrams per litreg / ha or g ai / ha = Amount of active ingredient applied in grams per hectaremg / ha or mg ai / ha = Amount of active ingredient applied in milligrams per hectare

6. A fungicidally effective composition comprising a systemic fungicide; and salicylic acid, salts or analogues thereof.
7. The composition as claimed in claim 6, wherein the composition further comprises an agriculturally acceptable excipient.
8. A method of controlling fungal disease in a plant, a crop, or a part thereof, or fungal infestation of a plant, a crop, or a part thereof comprising applying to a locus or the plant, the crop, or a part thereof a fungicidally effective combination comprising a systemic fungicide; and salicylic acid, salts or analogues thereof; or a composition comprising said combination.
9. The method as claimed in claim 8, wherein the systemic fungicide is applied at a rate of about about 0.1 g ai / ha to about 2000 g ai / ha.
